The whole welding process of galvanized steel wire mesh does not need special technological methods, good weldability. However, in a few cases, the welding process will present difficulties: the converter steel produced by the old smelting method has high nitrogen content and high impurity content, resulting in high cold brittleness, added aging sensitivity, lower quality of welded joints, and poor weldability.

The coating on the surface of the welding core is called the coating. The coating of electrode plays a very important role in the welding process. If the photoelectrode without drug skin is used for welding, in the welding process, oxygen and nitrogen in the air will invade a large number of molten metal, metal iron and beneficial elements such as carbon, silicon, manganese oxidation and nitriding to form various oxides and nitrides, and residual in the weld, resulting in slag inclusion or cracks in the weld. The gas in the weld pool may produce a large number of pores in the weld. These factors can greatly reduce the mechanical properties of the weld and make it brittle.

The characteristics of galvanized hexagonal net: easy to use; Save transportation costs. It can be shrunk into small rolls and involved in moisture-proof paper packaging, taking up little space. Coating thickness uniformity, stronger corrosion resistance; The construction is simple and does not require special technology; Strong resistance to natural damage and corrosion resistance and adverse weather effects; Can withstand a large range of deformation, and still not collapse. It has the function of fixed heat preservation and insulation.

A pet carrier can be used as an indoor or outdoor pet house. The dog cage is equipped with a fixed food basin and water fountain, and the foot plate pet cage rubber pad has bayonets on four sides to be splintered. It can be spliced, cut and disassembled according to the size of the cage. It is convenient and easy to clean. It can solve the problem of pinching the feet of the puppies in the ordinary cage and prevent the puppies from causing adverse reactions in the development. The dividers are breathable and comfortable, and can be used as heat shields for pets in summer. A puppy with small feet, no feet, no pinching.

Cold galvanizing (galvanizing) is in the plating tank after the current unidirectional, so that the zinc gradually plated on the metal surface, slow production speed, uniform coating, thin thickness, usually as long as 3-15g, bright appearance, poor corrosion resistance, usually a few months will rust. Compared with hot dip galvanizing, the production cost of electric galvanizing is lower.

The wire used for wire mesh is made of low carbon steel wire, medium carbon steel wire, high carbon steel wire, stainless steel wire and other materials woven or welded. Production technology: general braid, embossed braid and spot welding type. If the steel wire as the material, after the equipment processing into a network, so called wire mesh.

1, stress relief before plating where the maximum tensile strength is greater than 1034Mpa key and important parts before plating should be at 200±10℃ stress relief for more than 1 hours, carburizing or surface quenching parts should be at 140±10℃ stress relief for more than 5 hours.

Breeding cattle and sheep with barbed rope effect or better, because the advantages of barbed rope more. Then the barbed rope used for animal husbandry effect is good?
